Could you clarify or show me a picture of the resistor installed at the eol looks like? Do you connect the resistor to just the wires or hook into the no / c terminals of the smoke detector itself? Thank you.
The difference between using 2 wire smokes and 4 wire smokes is with 2 wire smokes all smokes will come in as a system fire signal and 4 wire smokes can be used to trip zone inputs and will annunciate the smokes if each smoke has it's own zone.
For 2 wire smokes program pgm2 as type 04 9 2-WIRE SMOKE ) in section 006, connect the negative smoke to pgm 2, connect the positive to aux+ and install a 2.2k eol resistor at the last smoke.
For 4 wire smokes program pgm2 as type 02 ( sensor reset ) IN SECTION 009, PROGRAM THE ZONE TYPE AS 08 ( 24 HOUR fIRE ) IN SECTIONS 001 - 004, connect the smoke power to aux+ and pgm2 negative, connect your smoke detector to the zone input and install a 5.6k eol at the smoke
